Thermostat housing complete from the junkyard for 10 dollars
it was super dirty
the thermostat had broken off .
So with a big flat head screwdriver pry it out.
popped off like a charm
stick the thermostat cover and the housing in a sand blaster
if not scrub them simple green and scotch bright.
well worth the effort
cut the snout for the throttle heater hose
now punch out the inner sleeve
part in a vice and about to drill it.
tap by hand
hole tapped
hole plugged
this port that has been pointed out is m12x1.5
the rest are m14x1.5
one of my holes was really gummy so i chased the thread with the tap.
make sure your tap is clean
remove your afm and stock airbox
remove your rubber intake
remove the coolant hoses on the throttle body
there are 3 torx screws on the plate going into the throttle body
pick out any crap out of the middle of the 3 torx bolts
I sawed off the tubes and then sanded the plate down and filled them with jb weld
new plate
the idea behind this was to make it look like the car was never missing anything.
and just put a bolt in the back of the block to plug that coolant port
you can spot in this picture below in a green circle
its either a m12x1.5 or a m14x1.5
